Building on the 1962 Glassco Commission report, this article argues that the duality of collective and individual ministerial responsibility in the Canadian Westminster model is under-recognized and remains highly relevant. While reforms since the 1960s favoured individual responsibility, the growing impact of information and communications technologies (ICTs) gives renewed significance to collective responsibility. This article reviews accountability challenges arising from ICT-influenced changes in the federal government's organization and relationships, including the shift from a traditional vertical departmental model towards an increasingly horizontal one. Accountability for this re-collectivized environment risks ineffectiveness for two reasons: the prime minister's view of his own role, and Parliament's difficulty in dealing with horizontal issues. If the risks are not recognized, Canadian democracy will be diminished.
